Universe Sandbox Wiki

A Fragment in Universe Sandbox is a simulated object that is too small to have a significant gravitational effect on other objects. Fragments are produced by processes like collisions, Roche fragmentation, and friction fragmentation, and are also used to represent smaller Solar System objects.

Properties Panel[]

The properties panel for a Fragment object will include the following tabs:


Fragment objects have the following characteristics:

  • They are non-attracting objects, meaning that they do not exert a gravitational force on other objects in the simulation.
  • They are attracted objects, meaning that they feel the effects of gravity from other attracting objects in the simulation.
  • They have no calculated orbital elements, and their orbit will not be displayed.
  • They can collide with other objects.
  • They have a single Surface Temperature rather than a two-dimensional simulation of temperature across the surface.
